Verified step by step guidance

Step 1: Begin by identifying the organ in question, the gallbladder, and its anatomical location. The gallbladder is a small, pear-shaped organ located beneath the liver.
Step 2: Understand the relationship between the gallbladder and the liver. The liver produces bile, a substance essential for the digestion and absorption of fats.
Step 3: Learn the primary function of the gallbladder. Its role is to store bile produced by the liver and concentrate it by removing water and electrolytes.
Step 4: Recognize the process of bile release. When fatty foods enter the small intestine, the hormone cholecystokinin (CCK) signals the gallbladder to contract and release bile into the duodenum via the bile duct.
Step 5: Compare the gallbladder's function to the other options provided in the question. Filtering toxins, secreting insulin, and producing digestive enzymes are functions of other organs (e.g., liver, pancreas), not the gallbladder.
